"I stumbled across the D-Line range after I'd been to Richer Sounds and got an astronomical quote for a Surround Sound install. I carried out the whole job (speaker wiring to a 5.1 set-up in the living room) myself, and I'm really pleased with it. The D-Line range does not drive you round the bend, it helps you get round them (tidily, and professionally).
Performance / Reliability only got 4 stars because a couple of the external bend brackets cracked slightly upon fitting. (negligible impact on overall finish, however)"
